A cigarette filter includes a multiple section filter which reduces the level of predetermined smoke constituents. The filter includes a fibrous filter plug section, a selective adsorbent section, and a general adsorbent section co-axially aligned in tandem. The selective adsorbent section includes a selective absorbent material which is a phenol-formaldehyde resin matrix surface-functionalized with mainly primary and secondary amine functional groups which removes specific smoke constituents from the tobacco smoke. The general adsorbent section is a material capable of adsorbing a range of chemical compounds without a high degree of specificity.

Cigarette filter

A non-combustible smoking article is provided in which a flavor generating medium, such as a commercially available cigarette, is heated with a fuel element including a liquid fuel therein to generate flavors or other components in vapor or aerosol form. A reusable fuel element is inserted in one end of a tubular member and a flavor generating medium, such as a cigarette, is positioned in the opposite end of the tubular member. Spacing between the fuel element and the cigarette is sufficient so that the cigarette is not lit but hot gases come into contact with tobacco or the like in the cigarette to vaporize the flavor components therein.
